Dear all
The tester doesn't turn not. When I press the rotary button the LCD lits and as soon as I release the button it turns off.
I tried to reprogram the chip using the files from mega328_st7565_kit (the last ones on the site).
TransistorTester.eep dated 4/21/2016
TransistorTester.hex dated 7/9/2016
but I do not know it it was success or not here is my result.

avrdude done. Thank you.
I got a spare blank chip. do you think I should try with that one? In case it doesn't work will I be able to reprogram my spare for use with arduino?
I'm sorry to be this cheap but where I live those chips are not easy to come by and bringing them in here is expensive.
Thank you all for your help
